pentobarbital sodium 30 mg/kg after 20 min, their chests were opened after anesthesia, and hearts were taken out quickly, immersed in Kreb's-Henseleit (K-H) perfusion solution as cooled with ice, after aortic cannulation, the hearts were placed in ex vivo heart perfusion device with constant temperature and constant pressure. Referring to the document (Chinese Journal of Pathophysiology, 1987, 3:154-158), the hearts were perfused by Langendorff method at 37° C., in which the 3 drug-administrated groups were subjected to calcium paradox plus the compound of the present invention 32 mg/L, the normal control group was subjected to a continuous perfusion for 35 min with calcium-containing Kreb's-Henseleit solution, the effluent of coronary artery of the last 20 min was collected, the other 5 groups were subjected to a perfusion for 10 min with calcium-containing K-H solution to reach stable state of heart, perfusion for 5 min with calcium-free K-H solution, then perfusion for 20 min with calcium-containing K-H solution again, so that calcium paradox models were established by such perfusion procedure, in which the positive control group was subjected to perfusion solution with 2.1 mg/L iproveratril in whole procedure, and the drug-administrated groups were subjected to perfusion solutions to which 32 mg/L sodium tanshinone IIA sulfonate hydrate was added separately. The effluent of coronary artery of 20 min when calcium-containing perfusion solution was restored was collected, the protein release amounts mg/min/g drywt and cardiac muscle tissue calcium uptake μmol/g drywt in the collected coronary artery effluents were measured according to the reference document. It is found that the result differences from the drug-administrated groups are significant (P<0.01) compared with the calcium paradox group, see Table 5 and Table 6. -
